The function of the cofunction of or something similar... (forgot how it was worded) and would something like -2sin(4x)sin(-2x) be the same as 2sin(4x)sin(2x)

And, Secant and Cosecant are cofunctions. You can use this mnemonic to remember the properties of trigonometric cofunctions.
Sine and Cosine are Co-functions. Meaning, In the same way, Tangent and Cotangent are cofunctions. And, Secant and Cosecant are cofunctions. Ah. So the statement "The function of Would = the cofunction of ? =)
